Granted: 2008-03-11
Abstract: An in-line cord ground fault circuit interrupter which contains within a common housing the sensing unit and the tripping relay usually found separately packaged at a remote location. The fixed contacts are mounted on fixed contact arms mounted adjacent one surface of a printed circuit board with the movable contacts mounted on movable contact arms mounted adjacent the second surface. The tripping relay operates an armature between an open and a closed condition and by cams on the arms of the armature opens and closes the movable contacts with the fixed contacts. The two portion housing allows the components of the interrupter to be mounted on one portion of the housing which also supports the line and load conductors making assembly of the rear housing portion to the front housing portion easy. A stop member and a positioning post are provided on the interior of the front cover to check the position of the armature in the non-energized state to verify proper contact placement and gaps.

Abstract: A tubing rotator and hanger connects to a wellhead having a wellhead flange. The rotator has a main body which includes a rotator flange mountable on a top side of the wellhead flange. A bore extends through the rotator body for inserting a mandrel therethrough. A load shoulder on a top end of the mandrel is supported by bearings on the rotator body. A removable split ring is located within an annular recess around the top end of the mandrel for connecting the mandrel to the load shoulder. A dognut is connected to a bottom end of the mandrel such that the dognut is disengaged from the wellhead during rotation of the tubing. A gear set within the rotator body rotates the mandrel in relation to the rotator body for rotating the tubing. A pair of pressure test ports connect an inner face of the rotator body to an outer face of the rotator body for monitoring pressure within the tubing rotator and hanger. A method is provided for removing the rotator body from the wellhead. The method includes connecting a pick up sub to an upper end of the mandrel for raising the mandrel such that the split ring may be removed. The mandrel is then lowered such that the dognut is seated within the wellhead. The pick up sub is then disconnected so the rotator body may be lifted from the wellhead.

Title: Computer security using virus probing
Inventor: GROSSE ERIC
IPC: G06F21/56
Filed: 1998-12-01
Granted: 2002-01-01
Abstract: A technique for determining whether particular clients within a computer network are universally configured in accordance with the desired network security features of the computer network. A probe is randomly inserted within incoming files, e.g., at a firewall in the computer network. The probe is configured as a function of a particular execution task, e.g. a known virus, such that in a properly configured client the probe will not execute and the firewall does not detect a security breach. However, if the client is misconfigured, i.e., not in compliance with the standard network security features, the probe will execute and trigger an alarm in the firewall indicating that the client is vulnerable to a security breach. Advantageously, a network security administrator can take appropriate action to correct those clients which are misconfigured.

Title: Fingerprint reading apparatus
Inventor: AOKI HISASHI
IPC: A61B5/117
Filed: 1999-03-11
Granted: 2004-02-10
Abstract: A two-dimensional photosensor (2) is formed on a surface light source (1), a nd a transparent conductive layer (3) made of ITO or the like is formed on the two-dimensional photosensor (2). The transparent conductive layer (3) dissipates static electricity and is grounded. Even if a finger in contact with the transparent conductive layer (3) on the two-dimensional photosensor (2) is charged with static electricity, this static electricity can dissipate via the transparent conductive layer (3). When the transparent conductive layer (3) is divided into two layers, and the finger simultaneously touches the two transparent conductive layers, a fingerprint reading start signal is obtained. Even if, therefore, the finger is charged with static electricity, the two-dimensiona l photosensor can be prevented from malfunction or damage by the static electricity. When a target object in contact between the transparent conductive layers is a copy having a different resistance value, reading is not performed, and the reliability can improve.

Abstract: The present invention concerns a method for producing a corrugated pasta sheet, facilitating the adherence of the sauce to the surface, in which the pasta sheet is obtained by forcibly extruding the dough through a slot in a die plate, comprising the stages during which at least one surface of the sheet is crimped repeatedly using at least one raised arm-type flexible, elasticized blade whose free end comes into contact with the sheet. The blade is inflected reciprocally by the dragging action exerted on it by the sheet as it passes through the slot and by the returning action produced by its elastic properties.
